Embodiment approach

[0018] In the embodiment shown in the schematic diagram, the solid line in the figure is an above-ground passage, and the dotted line is an underground passage. For the convenience of description, the intersections of T-shaped roads are indicated by A, B, and C, and the entrances and exits of tunnels are indicated by boxes and arrows. The numbers in the boxes indicate the serial numbers of the entrances and exits, and the small arrows in the figure indicate road signs.

[0019] B, C intersection:

[0020] Set up a horizontal left-turn underground passage: According to the practice of driving on the right, people and vehicles enter the No. 1 entrance approach road at a distance of more than 150 meters from the B intersection, go forward along the tunnel to the left, and pass through the horizontal tunnel to No. 1 exit out.

[0021] A, C intersection:

[0022] Set up a vertical left-turn underground passage: people and vehicles drive towards the T-shaped intersection, enter th...

Abstract

The invention belongs to road technology field. The essential of the invention is that there are two left turning underground passage on landscape orientation and on vertical orientation at the T-shaped crossing, and each passage is dual passage. On the landscape orientated passage, passerby and cars are coming from the landscape orientated passage, enter into the entrance of the left turning underground passage and go to the exit along the landscape orientated passage. On the vertical orientated passage, passerby and cars are coming from the vertical orientated passage, enter into the entrance of the left turning underground passage, pass through the left front exit along the passage, turn right front and keep going along the passage, pass the landscape orientated passage, then turn left front and go out from the exit. The dual passage means that the left side of each passage is for passerby, and the left side is for motor vehicles. The invention solves the problem of stop, run and wait of the road, saves much time of the passerby and vehicles, increases the passing speed, cancels traffic lights and traffic police, and saves cost.

Description

Technical field: [0001] The invention belongs to road structures, in particular to two left-turn underground passages at a T-shaped intersection where people and vehicles are unimpeded. Background technique: [0002] Traffic congestion is common in large and medium-sized cities in my country, especially the phenomenon of traffic congestion at T-junctions of main traffic arteries. Although the ring-shaped reversing island cross-reversing technology is adopted, the problem of partial parking and other roads is solved. However, there is a lack of sense of security when crossing and reversing, and it takes up a large area, so it is not suitable for widespread implementation; the technology of traffic light control crossing and reversing is generally implemented, which solves traffic jams and chaos, and realizes orderly traffic, but there is no such thing as stopping and other roads. solve. [0003] According to information reports about underground passages: generally all focu...
